How to limit Access to control panel

-- HikaShop version -- : 2.6.0
-- HikaMarket version -- : 1.6.7

Hello,

two questions :
1/ when a vendor is in the product creation page, the arrow on top left "retour" enable the vendor to go back (even if he didn't come from it) to the product listing and then if he clicks again on it he can go to control panel. I would like to avoid this, and potentially completely getting rid of this "back" button.
2/ in the control panel itself :
2.1/ I would like to hide the "customer" button ( I don't want the vendor to have any access to any customer vendor). how to do this?
2.2/ in the "orders" detail, how can I hide the information about the customer (name, email, adress,..)
regards

Hi,
I have successfully done the 1st modification, thanks.

for the second, I may have not understood. The only place where I saw a "customer" in ACL is in the order/edit/customer which I unchecked. But the button "customer" still appears in the cPanel.
I could actually make it disappear in an other way by modifying the view "cpanel" and putting a condition on the $btnName like this (on top of empty($btn), in line 19) :

if(empty($btn) or $btnName=='user')
continue;

however it seems to me pretty "rough"; could you (re)explain a better solution?

regards.

Ok, I could do it with using the "user" fields. I can't say that it was obvious that this "user" field would change the "customer" access in the cPanel. Maybe something to improve in the documentation?

Thank you.
